BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a knitted fabric consisting of first and second knitted strips which are connected to each other in places.

0002

BACKGROUND OF THE INVENTION It is known to produce two separate knitted strips simultaneously and parallel to each other on a knitting machine and to join them together in places to obtain a double layer knitted fabric which is subdivided into individual pockets. Knitted fabrics are also known in which two knitted fabric strips are connected to each other by pile threads extending between them, and the reinforcement of the pile threads maintains the mutual spacing of the strips.

0003

[Problem to be Solved by the Invention] The problem underlying the present invention is to manufacture knitted fabrics of the first type with a desired shape on a knitting machine so that the knitted fabrics are stable in all aspects. The idea is to have a knitted wall.

0004

In order to achieve this object, according to the invention, at least one knitted strip extends between the first and second knitted strips and is knitted-technically connected thereto. A third knitting strip interconnects the two knitting strips at a distance.

[0005]

In the knitted fabric constructed according to the present invention, the portions that connect the inner and outer walls to each other are also constructed as stable knitted strips, and are not composed only of individual binding yarns. Moreover, the inner wall is not later joined to the outer wall by stitching, but rather by knitting technology, allowing the knitting machine to produce knitted fabrics in one piece.Modern programmable flat knitting machines are capable of tertiary knitting. To economically enable integral production of originally complicated knitted fabrics.

[0006]

[Embodiment] In the knitted fabric constructed according to the present invention, the third knitted strip extends, for example, in a meandering manner between the first and second knitted strips, and the knitting technique is used to connect these at a plurality of locations. Make sure it is connected to the knitted strip. However, the connection of the first and second knitted strips, which determines the outer surface of the knitted fabric, may include a plurality of additional knitted strips, which are connected in a knitting technique to the first and second outer knitted strips at a distance from each other. It can also be done in pieces. The two outer knitted strips and the additional inner connected knitted strip are also constructed as patterned strips by means of stitch reduction or addition or known gusset formation, which patterned strips impart the desired specific properties to the entire knitted fabric. It is possible to give a three-dimensional shape. This is achieved by manufacturing the knitted strips that serve the connection in different partial lengths or full lengths or widths.
It can be carried out. Individual knitted strips can also be produced with different strengths and different thread materials. The knitted fabric constructed according to the invention can be used for clothing and also for technical constructions in which the knitted strip can be subsequently processed and the voids formed can be at least partially filled.

The production of knitted fabrics on a two-needle bed flat knitting machine with a stitch transfer device can be carried out in various ways. 1:1
Two embodiments for knitted fabrics having one or one course of knitted strips are indicated in claims 7 and 8.
